.i'b aZZ whom it may concern:

I Be it known that I, EDWARD S. Fonn, a citizen of the United States, residing at (Janton, in the county of Stark and State of @hio, have invented a new and useful Roller- Bearing, of which the following is a specification.

The present invention relates to improvements in roller bearings and has more especial reference -to a one piece self-retaining roller cage formed from sheet metal.

The object of the invention is to provide a simple construction adapted to be stamped from a single sheet of metal and bent into proper form to strengthen the structure and retain the rollerstherein;

A further object is the provision of a roller bearing cage which will permit of easily assembling the rollers therein and which will retain the rollers after being assembled.

A still further object is the provision of a roller bearing cage of this character which will be inexpensive and simple to manufacture and eliicient and durable in use.

With these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of construction may be made within the scope of the appended claims, without departing from the spirit or sacriicing any of the advantages of the invention.

In the accompanying drawings:

Figure 1 is a side elevation of a roller bearing embodying my invention, parts being broken away for the purpose of illustration, the outer race ring being omitted.

Fig. 2 is a transverse sectional view through the roller bearing.

Fig. 3 is a detail perspective view upon an enlarged scale of a portion of the cage.

Similar numerals of reference indicate corresponding parts throughout the several figures of the drawings:

Referring more especially to the construction illustrated in the accompanying drawings, the numeral 1 indicates the usual inner bearing ring or cone upon which the rollers 2 are supported in the usual manner, the outer surface of said cone being of the Specification of Letters Patent.

with the adj aproper contour to conform The cent contacting faces of the rollers.

'cago which is for the purpose of retaining conical portion 4E provided at properly spaced intervals with the longitudinally disposed roller receiving slots 5, longitudinal spacing bars 6 being thus formed between the roller receiving slots 5.

An outwardly pressed pocket 8 is formed at each extremity of each of the slots and arranged to receive the pintles 9 which are formed upon the rollers. Au outwardly flared flange 10, projecting toward the center of the bearing is provided uponeach. longitudinal edge of each of the bars 6, said flanges being formed from the material which is out out to form the slots 5.

Each edge of the cage is turned outwardly away from the center of the bearing forming straight annular reinforcing flanges 11 at the ends of the cage. It will be understood of course that the flanges are preferably curved to conform with the contour of the rollers, thus forming a trough of proper size and shape between each adjacent pair of bars 6 in which a roller is received, the flanges 10 preventing the roller from falling through the slots 5 and the pocketsS retaining the rollers within the troughs thus formed.

By this construction a cage is formed which is simple and inexpensive and which is not unnecessarily weakened by having parts cut out therefrom, the cage and rollers forming a single unit which may be easily and readily removed from a bearing orplaced therein. It will also be understood that although in the drawing a conical bearing provided with conical rollers is illustrated that the rollers may be of cylindrical form and the cage properly formed to retain said rollers within a cylindrical bearing without departing from the spirit of the invention.

Although the drawings and above specification discloses the best mode in which '1 have contemplated embodying my invention I desire to be not limited to the details of such disclosure, for in the further practical application of my invention, many changes in form and construction may be made, as circumstances require or experienre suggests, without departing from the spirit of the invention, within the scope of the appended claims.

I (claim:

I. An inl'egral metal cage for roller bearings having a series of spaced longitudinally disposed slots formed therein, inwardly disposed flanges provided along the edgesol? said slots and outwardly pressed pockets forined at the ends of said slots and adapted to surround the pintles ol? the rollers.

2. An integral metal cage For roller hearings having a series of spaced longitudinally disposed slots formed therein, 5].- wnrdly disposed flanges provided along the edges of said slots outwardly pressed pork ets Formed at the ends of said slots and adapted to surround the pintles of the roll-- ers, and outwardly disposed, straight unnulur flanges formed at the ends of said. Page.

in testiimmy that I claim the above, l have hereunto. subscribed my name.
